HealthTracker Plugin Professional plugins for Nagios based monitoring

Why HealthTracker? Integrated view on all NetApp systems Integration into different monitoring platforms Define the level of detail Individual processing of data Individual adaptations Scalable solution for any enterprise

Overview of available Plugins Caches Buffer Cache, FlashCache and FlexCache Hardware Broken disks, temperature, cooling-devices, power-supplies, NVRAM Network Stats per interface (ifnet): Bytes and packets read and sent, errors per second, multicasts, collisions Performance Operations per second (HTTP, CIFS, ...), transfer-rate (network, disks, ...), utilization in % (processor, disk), performance per volume (latency, IOPS)

Overview of available Plugins Snapshot Available snap-size and transfer-errors from SnapMirrors and SnapVaults, utilization of the SnapReserve – additional criteria are the age or name of Snapshots, which can be used to monitor Snapshot-backups whether they are up to date or not. Storage Available space for aggregates, volumes and quotas Status Global system-status, cluster-status, status from iSCSI-adapters (online/offline), RAID-status of aggregates and volumes Management High-level overview for decision-makers Other Other tools, modules and documentation

Details of all plugins (Basic) check_netapp_health monitors the system health. Sends an alarm if the system health status is anything other than 'ok'. check_netapp_spare monitors the status of the spare-low condition (alarms if there is no suitable spare disk available). Disk checks for failed/offline disks on the filer. Head monitors the heads hardware objects (fans, NVRAM, power-supplies, health- state, temperature-sensors NetPort checks if the network-interfaces are enabled or not Snapshots checks, if the snap-reserve is still sufficient. Thresholds are set in percent; performance-data can be either in percent or absolute (Byte). Additional criteria are the age or name of the snapshot. This can be used for monitoring snapshot-backups and whether they are up to date or not. Also can be used to find snapshots related to a specific application like SNMV and check all volumes for left- over snapshots. Uptime checks the seconds since last reboot. Usage checks the used space in volumes and aggregates. Thresholds can be set in GB or percent.

Details of all plugins (Advanced) AggregateState checks the aggregates-state. Alarms if they are not online (configurable) check_netapp_anycli for building checks with simple CLI-commands. check_netapp_cluster checks the status of the high availability service (connected, taken over, takeover failed, ...). DiskCount counts the number of disks matching defineable criteria (disk-type, container (spare, ...), storage-pool). Mostly used to monitor the number of spare- disks of a certain type. DiskPaths Checks if each disk has two paths (A/B, B/A). IfGrp checks if an interface-group has enough links in up-state to still be redundant. LunState checks the LUN-states. Alarms if they are offline. NetInterface checks if a network interfaces current-port is not equal to its home- port (output of the CLI command `network interface show -is-home false`). Can also check it's operational mode (up/down). StorageUtilization Storage Utilization answers the question, “Am I effectively using the storage capacity available to my applications.

Details of all plugins (Advanced) OvercommitAggr Returns a list of aggregates together with their overcommitment in percent. Overcommitment is the relation between the aggrgates size and the total of all its (thin provisoned) volumes sizes. Raidstatus alarms, if one of the RAIDs is degraded. ShelfBay checks, the shelf- and disk-port status. Can alarm BYP-status disks. SnapMirrorMetrics checks and logs SnapMirrors (including type Vault): lag-time, last-transfer-duration, last-transfer-size SnapMirrorState checks and logs for SnapMirror (including type Vault): health, mirror-state UsageTrend checks the time how long ist would last until an aggergate or volume is full, if the trend of the last 48h (configurable) would continue. VolumeAutosize checks a volumes total-size and alerts when the volume is close to being full relative to the autosize maximum. VolumeState checks the volume-states. Alarms if they are not online (configurable). Vserver monitors the admin-state or the operational-status of a Vserver (running, stopped, inconsistent or defunct)

Details of all plugins (Performance) BadlyPerformingDisks checks all disks in a NetApp system or in a specific raid- group. If a certain number of them performes badly (=has a high utilization) an alarm is send. BufferCache checks several metrics of the system buffer cache (=system memory) like Buffers being read, Buffers being written, Empty (unused) buffers, Buffers with modified data, Buffers associated with CP IO, ... FlashCache checks several metrics of the external FlashCache (PAM II) like External cache hit rate, Average latency of read I/Os, Number of wafl buffers served off the external cache, ... LunLatency Checks the 'latency' and 'operations per second' (ops) per LUN. Shows details for total, read, write and other. NetApp recommends monitoring latency as the primary performance indicator. NVRAM checks data-rates and latency of the NVRAM. PerfCpu checks one or all processors in a NetApp system for their utilization. PerfDisk checks all disks in a NetApp system for their utilization (Percentage of time there was at least one outstanding request to the disk). Optional the check can be limited to the disks of a single aggregate.

Details of all plugins (Performance) PerfHostadapter checks and counts rates per host adapter (Fibre Channel, Serial Attached SCSI, and parallel SCSI). PerfIf checks and counts transfer-rates and errors per network-interface (ifnet). Especially useful for monitoring 10GbE-ports. PerfLif checks and counts transfer-rates and errors per network-interface (lif) for DataONTAP 8.2.x. or higher. PerfSys checks various performance counters of the NetApp-system (mostly operations/second and transfer-rates). Counters supported: net_data_sent, dafs_ops, total_ops, disk_data_written, net_data_recv, cifs_ops, streaming_pkts, http_ops, nfs_ops, fcp_ops, disk_data_read, iscsi_ops PerfTcpIp checks CRC errors and packets send/received for both the IP and TCP layer. PerfVolume checks the 'latency' and 'operations per second' (ops) per volume. Shows details for total, read, write and other. NetApp recommends monitoring latency as the primary performance indicator. Wafl reads WAFL performance-counters like cp_count twice and calculates the rate of CPs per second. Different types of consistency-points (wafl-timer, back-to-back, ...) can be checked. The information gathered from this plugin corresponds to the CPty-column of 'sysstat -x 1'.

Details of all plugins (MetroCluster) check_netapp_mc_config checks a metro-clusters mode and configuration state. ClusterPeerHealth checks the health of cluster peer relationships by evaluating several ping- and health-status. SyncMirror checks the mirror-status on Metro Cluster aggregates.
